The Crossover timer has a diagonal flow of different colored oils to create an interesting visual effect. A calming and mesmerising device that can be used by those affected by sensory overload. This sensory toy the perfect addition to any sensory kit. Great for the classroom or even beside the bed to help children relax and calm. They also make the perfect desk accessory and a great Christmas present for young and old.
Oil Timers are not measured by strict time, rather they are controlled by the elements. On a hot day they will run faster, on a cold day or if kept in the fridge they will run slower. They are very relaxing to watch the drips moving and when they have all reached the bottom, flip it over to begin again. They are a great sensory toy, both calming and relaxing and also quiet addictive.
